Turning on/shutting down issue

Hello,
I cannot turn on my PC at all until I unplug something, like when I try to turn it on it doesn't work, I unplug the Display port then I turn it on and after it turns on I replug it.
I also have problems with shutting down, I sit the pc down from Windows and it shows me the "shutting down" thing and then it suddenly shuts off like it's been unplugged from the wall.
I have my AC, phone, monitor, router and PC.
And I'm using some extensions and adapters because the wall plug is pretty far.
By the way I replaced my Mobo CPU, ram and GPU because the previous build had other problems.

Thanks in advance.

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

PC shuts down after turning it on

Hello. I have a problem with my pc. I have windows 10 installed, and have formatted and installed windows all over again trying to fix this problem but it didn't do it. When I turn on my pc, the windows logo appears for a few seconds and then the computer shuts off. When I press the power button one more time it turns on and loads windows perfectly. This is a problem for me because I cannot hibernate anymore, since everytime I hibernate and then press the power button for the first time the computer shuts off. I don't know what else to do. What do you suggest? Has this ever happened to anyone? Thanks.
